I'm just logged in (past lobby), i have custom settings but they are set to as low as possible. Using directx. My cpu is very very high and so is my memory usage (in the past, i saw it go to 1GB of memory usage since i've swapped to windows 8.1). I am NOT running a script bot.

Last week when I did performance profiling the CPU overhead of running a decently optimized script bot was using only 10% of the cpu cycles overall. The other 90% appeared to be coming from the game itself.
